On ThunderX 88xx pass 2.x chips when TSO is offloaded to HW,
HW posts a CQE for every TSO segment transmitted. Current code
does handles this, but is prone to issues when segment sizes are
small resulting in SW processing too many CQEs and also at times
frees a SKB which is not yet transmitted.
This patch handles the errata in a different way and eliminates issues
with earlier approach, TSO packet is submitted to HW with post_cqe=0,
so that no CQE is posted upon completion of transmission of TSO packet
but a additional HDR + IMMEDIATE descriptors are added to SQ due to
which a CQE is posted and will have required info to be used while
cleanup in napi. This way only one CQE is posted for a TSO packet.

There is a issue in HW where-in while sending GSO sized pkts
as part of TSO, if pkt len falls below configured min packet
size i.e 60, NIC will zero PAD packet and also updates IP total length.
Hence set this value to lessthan min pkt size of MAC + IP + TCP
headers, BGX will anyway do the padding to transmit 64 byte pkt
including FCS.

The ethtool_ops .get_regs function attempts to read the nonexistent
register NIC_QSET_SQ_0_7_CNM_CHG, which produces a "bus error" type
OOPs.
Fix by not attempting to read, and removing the definition of,
NIC_QSET_SQ_0_7_CNM_CHG. A zero is written into the register dump to
keep the layout unchanged.

When SQ/TXQ is reclaimed i.e reset it's stats also automatically reset
by HW. This is not the case with RQ. Also VF doesn't have write access
to statistics counter registers. Hence a new Mbox msg is introduced which
supports resetting RQ, SQ and full Qset stats. Currently only RQ stats
are being reset using this mbox message.

On 88xx all LMACs in a BGX will be in same mode but on 81xx
BGX can be split as two and there can be LMACs configured in
different modes.
These changes move lmac_type, lane2serdes fields into per lmac
struct from BGX struct. Got rid of qlm_mode field which has become
redundant with these changes. And now no of valid LMACs is read
from CSRs configured by low level firmware and figuring out the
same based on QLM mode is discarded
